Dysmenorrheic and nondysmenorrheic women in the follicular, luteal and menstrual phase of their menstrual cycle participated in a stressful laboratory procedure. Pulse rate, pulse volume and skin conductance were measured continuously during baseline, during confrontation of three stressful tasks (i.e. stress-reactivity periods) and following each confrontation (i.e. stress-recovery periods). The hypothesis that dysmenorrheic Ss in the menstrual phase of their cycle would show greater stress responsitivity was generally not confirmed, and the broader contention that women differ in their stress responsivity as a function of their menstrual cycle phase was shown to be of questionable validity.
